The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming our way.
Right off the bat, the first few days are a write-off. We’ve got tiny, weak swell and poor conditions keeping things flat and messy. It’s not until the morning of Saturday the 5th that we see something worth paddling out for. That’s a solid 3-day gap of nothing happening.
So, the first real hope is Karramarro on the morning of Saturday the 5th. We’re looking at a clean 4ft swell out of the northwest, and the wind is glassy. The period is a very long 14 seconds, which means real groundswell energy, but at a point break like this, that long-period groundswell should wrap in nicely and offer up some proper shaped waves. The combined energy reading of 410 is moderate, so there’s enough push. The water is running warm, about 4° warmer than normal for this time of year, which is notable. The crowd situation here is something to keep in mind – it’s listed as “often” busy, so expect company. This is the standout of the whole window. It’s for advanced surfers, and while the size is fine for most, the long period might make the paddle-out a bit tricky.
The swell builds into the afternoon of the 5th, hitting 5ft, but the wind swings onshore, which will chop it up. Not the best.
Sunday morning the 6th is also a good call. We’ve got 5ft out of the northwest with a 12-second period, and a clean, cross-off breeze. The energy is a strong 603, so there’s some grunt in the water. This is another moment where the point break should be working nicely, with clean conditions. It’s a solid runner-up to the Saturday morning session.
The following week gets a bit patchy. There’s some surfable waves around the 9th and 10th, but the quality is marginal. By the 10th afternoon, the swell jumps to 7ft, which is getting big for most, but the wind is cross and it’s a short period 8-second swell, so it’ll be a bumpy, lumpy mess – not really for paddling, more of a kite day.
After that, the energy drops off sharply. From the 11th right through to the 16th, it’s mostly tiny, weak swell with poor conditions. There’s a glimmer on the morning of Wednesday the 16th with a glassy 3ft, 12-second northwest swell, giving a moderate energy reading of 278. That’s worth a look if you’re desperate, but it’s nothing special compared to that opening weekend.
So if you’re keen, pencil in the morning of Saturday the 5th of September as your best bet. Sunday morning the 6th is the backup. The rest is mostly a waiting game.
Rusty.

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Karramarro is 3 km (2 miles) from Zarautz. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Zarautz. Zarautz has rooms for a wide range of budgets as well as car hire and transport links.
